Synthesis of highly efficient nitrogen enrich graphene eosin-Y coupled photocatalyst that uses solar energy in trifluoromethylation of benzaldehydes

Abstract

The production of trifluoromethyl groups on organic compounds by graphene-based photocatalysts is an emerging research area in the 21^st century. However, the pricey and poisonous nature of metal-based photocatalysts poses a significant barrier to the insertion of trifluoromethyl groups. Therefore, the trifluoromethylation of organic compounds and conversion into sustainable, greener chemicals via solar light irradiation is a hot and challenging topic. So, herein we developed a solar light-harvesting nitrogen enrich Eosin-Y functionalized graphene-based (NDGFE-Y) photocatalytic system with appropriate band gap and supported by UV-Visible, FTIR, XRD, and FE-SEM, Raman spectra and TGA curve. This prepared photocatalyst is a yardstick example for the photoinduced oxide CF₃SO₂Na to produce the CF₃ as an electrophilic radical, effectively making the trifluoromethylation of benzaldehyde and their derivatives.
